LL4902 is a high turns ratio (1+1 : 22) microphone input transformer with double Faraday shields. LL4902 was designed for a customer in 
Australia, and is probably suitable for a 75 ohm : 10k application. The LL4902 is discontinued and no data sheet is available, but we do 
actually have approx. 100 x (non-ROHS-compliant) LL4902 in stock.
